Rat Race

We got to go to the science center. They have this wonderful exhibit with this wheel for people to run in. The wheel provides the power to move balls up on a roller coaster ride. There must be at least a thousand feet of track, and different adventures for the balls to go through on their way back down. It’s like a giant sized marble works or something. I would love to have something like this to power the TV in my house, so the kids would have to run to keep it working. Most likely an exercise bike would be the better way to get that done, but this would be pretty cool too. Maybe one day I’ll take the time to figure that out. Perhaps it could be something other people would be interested in owning, and I could build a company around the concept. Not any time soon I’m afraid.
